Description
Translates OpenFOAM data to EnSight format.
An Ensight part is created for the internalMesh and for each patch.
Usage
\b foamToEnsight [OPTION]
Options:
- \par -ascii
Write Ensight data in ASCII format instead of "C Binary"
- \par -noZero
Exclude the often incomplete initial conditions.
- \par -noLagrangian
Suppress writing lagrangian positions and fields.
- \par -noPatches
Suppress writing any patches.
- \par -patches patchList
Specify particular patches to write.
Specifying an empty list suppresses writing the internalMesh.
- \par -faceZones zoneList
Specify faceZones to write, with wildcards
- \par -cellZone zoneName
Specify single cellZone to write (not lagrangian)
- \par -width \<n\>
Width of EnSight data subdir (default: 8)
Note
Writes to \a EnSight directory to avoid collisions with
foamToEnsightParts
